Not all fasts are equivalent. The duration of the fast depends upon the age of the patient, the nature of the disease and the amount and type of drugs previously used.
The duration is important, because long periods of fasting can be dangerous if undertaken without competent professional guidance.
It is, therefore, advisable to undertake a series of short fasts of two to three days and gradually increase the duration of each succeeding fast by a day or so.
The period of the fast, however, should not exceed a week of total fasting at a time. This will enable the chronically sick body to gradually and slowly eliminate toxic waste matter without seriously affecting the natural functioning of the body.
A correct mode of living and a balanced diet after the fast will restore vigour and vitality to the individual.
